为降低地膜覆盖栽培成本,进一步提高地膜利用率,促进增产增收。成都市第一农科所从1984年起对地膜覆盖栽培进行了深入研究,他们根据地膜覆盖栽培夏季蔬菜后,地膜还不很烂的现象,进行了连续免耕覆盖栽培秋淡季菜和冬春季菜的试验。实践证明,夏秋两季地膜可以避免雨水冲刷和淋溶,土壤也不致太湿,确保了秋冬季菜的播栽质量,减少了蔬菜病害发生,有利于蔬菜生长。土壤测定也证实,连续覆盖栽培两茬菜后,土壤仍
In order to reduce the cost of mulching cultivation, further improve the utilization of mulching film and promote the increase of yield and income. The first agricultural institute of Chengdu conducted an in-depth study on plastic film mulching cultivation since 1984. According to the phenomenon of non-rotten mulching after summer mulching with plastic film mulching, they conducted continuous no-tillage cultivation of autumn and autumn seasons and spring and winter Vegetable test. Practice has proved that the summer and autumn can prevent the rain film washing and leaching of the soil, the soil will not be too wet to ensure the quality of autumn and winter seeding, reducing the occurrence of vegetable diseases, is conducive to the growth of vegetables. Soil testing also confirmed that the soil was still covered after two consecutive cropping cultivation
